I70.40 — Unspecified atherosclerosis of autologous vein bypass graft(s) of the extremities
I70.40 is a non-billable header ICD-10-CM code for unspecified atherosclerosis of autologous vein bypass graft(s) of the extremities. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 inherited from the categories above I70.40
Also inherited, and the opposite of Excludes1: these conditions are not part of I70.40, but a patient can have both, so you may code both.
Written on I70 — Atherosclerosis
Other codes that can never be billed with I70.40
These codes carry an Excludes1 note pointing at I70.40. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I70.40 alone.
- I77.6Arteritis, unspecified
Risk adjustment
I70.40 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
I70.40 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
